Properties of @code{uicontrol} objects (@pxref{XREFuicontrol,,uicontrol}):

@table @asis

@anchor{XREFuicontrolbackgroundcolor}
@prindex uicontrol backgroundcolor

@anchor{XREFuicontrolbusyaction}
@prindex uicontrol busyaction
@item @code{busyaction}: @qcode{"cancel"} | @{@qcode{"queue"}@}
Define how Octave handles the execution of this object's callback properties when it is unable to interrupt another object's executing callback.  This is only relevant when the currently executing callback object has its @code{interruptible} property set to @qcode{"off"}.  The @code{busyaction} property of the interrupting callback object indicates whether the interrupting callback is queued (@qcode{"queue"} (default)) or discarded (@qcode{"cancel"}).
@xref{Callbacks, , @w{Callbacks section}}.


@anchor{XREFuicontrolbuttondownfcn}
@prindex uicontrol buttondownfcn
@item @code{buttondownfcn}: string | function handle, def. @code{[](0x0)}
For information on how to write graphics listener functions see @ref{Callbacks, , @w{Callbacks section}}.

@item @code{callback}: def. @code{[](0x0)}



@anchor{XREFuicontrolcdata}

@item @code{cdata}: def. @code{[](0x0)}



@anchor{XREFuicontrolchildren}
@prindex uicontrol children
@item @code{children} (read-only): vector of graphics handles, def. @code{[](0x1)}
Graphics handles of the uicontrol's children.


@anchor{XREFuicontrolclipping}
@prindex uicontrol clipping
@item @code{clipping}: @qcode{"off"} | @{@qcode{"on"}@}
If @code{clipping} is @qcode{"on"}, the uicontrol is clipped in its parent axes limits.


@anchor{XREFuicontrolcontextmenu}
@prindex uicontrol contextmenu
@item @code{contextmenu}: graphics handle, def. @code{[](0x0)}
Graphics handle of the uicontextmenu object that is currently associated to this uicontrol object.


@anchor{XREFuicontrolcreatefcn}
@prindex uicontrol createfcn
@item @code{createfcn}: string | function handle, def. @code{[](0x0)}
Callback function executed immediately after uicontrol has been created.  Function is set by using default property on root object, e.g., @code{set (groot, "defaultuicontrolcreatefcn", 'disp ("uicontrol created!")')}.

For information on how to write graphics listener functions see @ref{Callbacks, , @w{Callbacks section}}.


@anchor{XREFuicontroldeletefcn}
@prindex uicontrol deletefcn
@item @code{deletefcn}: string | function handle, def. @code{[](0x0)}
Callback function executed immediately before uicontrol is deleted.

For information on how to write graphics listener functions see @ref{Callbacks, , @w{Callbacks section}}.


@anchor{XREFuicontrolenable}
@prindex uicontrol enable
@item @code{enable}: @qcode{"inactive"} | @qcode{"off"} | @{@qcode{"on"}@}



@anchor{XREFuicontrolextent}
@prindex uicontrol extent
@item @code{extent} (read-only): four-element vector
Size of the text string associated to the uicontrol  returned in the form @code{[0 0 width height]} (the two first elements are always zero).

For multi-line strings the returned @code{width} and @code{height} indicate the size of the rectangle enclosing all lines.


@anchor{XREFuicontrolfontangle}
@prindex uicontrol fontangle
@item @code{fontangle}: @qcode{"italic"} | @{@qcode{"normal"}@}
Control whether the font is italic or normal.


@anchor{XREFuicontrolfontname}
@prindex uicontrol fontname
@item @code{fontname}: string, def. @qcode{"*"}
Name of font used for text rendering.  When setting this property, the text rendering engine will search for a matching font in your system.  If none is found then text is rendered using a default sans serif font (same as the default @qcode{"*"} value).

Programming Note: On systems that don’t use FontConfig natively (all but Linux), the font cache is built when Octave is installed.  You will need to run @code{system ("fc-cache -fv")} manually after installing new fonts.


@anchor{XREFuicontrolfontsize}
@prindex uicontrol fontsize
@item @code{fontsize}: scalar, def. @code{10}
Size of the font used for text rendering.  @xref{XREFuicontrolfontunits, , fontunits property}.


@anchor{XREFuicontrolfontunits}
@prindex uicontrol fontunits
@item @code{fontunits}: @qcode{"centimeters"} | @qcode{"inches"} | @qcode{"normalized"} | @qcode{"pixels"} | @{@qcode{"points"}@}
Units used to interpret the @qcode{"fontsize"} property.


@anchor{XREFuicontrolfontweight}
@prindex uicontrol fontweight
@item @code{fontweight}: @qcode{"bold"} | @{@qcode{"normal"}@}
Control the variant of the base font used for text rendering.


@anchor{XREFuicontrolforegroundcolor}
@prindex uicontrol foregroundcolor
@item @code{foregroundcolor}: def. @code{[0   0   0]}



@anchor{XREFuicontrolhandlevisibility}
@prindex uicontrol handlevisibility
@item @code{handlevisibility}: @qcode{"callback"} | @qcode{"off"} | @{@qcode{"on"}@}
If @code{handlevisibility} is @qcode{"off"}, the uicontrol's handle is not visible in its parent's "children" property.


@anchor{XREFuicontrolhittest}
@prindex uicontrol hittest
@item @code{hittest}: @qcode{"off"} | @{@qcode{"on"}@}
Specify whether uicontrol processes mouse events or passes them to ancestors of the object.  When enabled, the object may respond to mouse clicks by evaluating the @qcode{"buttondownfcn"}, showing the uicontextmenu, and eventually becoming the root @qcode{"currentobject"}.  This property is only relevant when the object can accept mouse clicks which is determined by the @qcode{"pickableparts"} property.  @xref{XREFuicontrolpickableparts, , @w{pickableparts property}}.


@anchor{XREFuicontrolhorizontalalignment}
@prindex uicontrol horizontalalignment
@item @code{horizontalalignment}: @{@qcode{"center"}@} | @qcode{"left"} | @qcode{"right"}



@anchor{XREFuicontrolinterruptible}
@prindex uicontrol interruptible
@item @code{interruptible}: @qcode{"off"} | @{@qcode{"on"}@}
Specify whether this object's callback functions may be interrupted by other callbacks.  By default @code{interruptible} is @qcode{"on"} and callbacks that make use of @code{drawnow}, @code{figure}, @code{waitfor}, @code{getframe} or @code{pause} functions are eventually interrupted.
@xref{Callbacks, , @w{Callbacks section}}.


@anchor{XREFuicontrolkeypressfcn}
@prindex uicontrol keypressfcn
@item @code{keypressfcn}: def. @code{[](0x0)}



@anchor{XREFuicontrollistboxtop}
@prindex uicontrol listboxtop
@item @code{listboxtop}: def. @code{1}



@anchor{XREFuicontrolmax}
@prindex uicontrol max
@item @code{max}: def. @code{1}



@anchor{XREFuicontrolmin}
@prindex uicontrol min
@item @code{min}: def. @code{0}



@anchor{XREFuicontrolparent}
@prindex uicontrol parent
@item @code{parent}: graphics handle
Handle of the parent graphics object.


@anchor{XREFuicontrolpickableparts}
@prindex uicontrol pickableparts
@item @code{pickableparts}: @qcode{"all"} | @qcode{"none"} | @{@qcode{"visible"}@}
Specify whether uicontrol will accept mouse clicks.  By default, @code{pickableparts} is @qcode{"visible"} and only visible parts of the uicontrol or its children may react to mouse clicks.  When @code{pickableparts} is @qcode{"all"} both visible and invisible parts (or children) may react to mouse clicks.  When @code{pickableparts} is @qcode{"none"} mouse clicks on the object are ignored and transmitted to any objects underneath this one.  When an object is configured to accept mouse clicks the @qcode{"hittest"} property will determine how they are processed.  @xref{XREFuicontrolhittest, , @w{hittest property}}.
